This is a summary of 1984 in music in the United Kingdom, including the official charts from that year.

1984 was a year of several huge selling releases, including at the time the biggest selling single ever. Six singles this year sold over a million copies, the joint highest number ever along with 1998. Out of the top 10 biggest selling songs of the 1980s, six of them all peaked in 1984 including the entire top 4.

One of the biggest bands of the year was Frankie Goes to Hollywood, a five-piece from Liverpool fronted by Holly Johnson. Their debut single "Relax" was banned by the BBC for sexually suggestive content, and was number 1 for five weeks. Their second single "Two Tribes" referenced the ongoing cold war and featured a music video of lookalikes of American president Ronald Reagan and Soviet leader Konstantin Chernenko violently fighting, and was number 1 for nine weeks in the summer, both songs selling over a million. In November they made chart history when their third single, "The Power of Love", also made number 1. They were only the second band in chart history to have their first three releases all go to number 1, following Gerry & The Pacemakers twenty years earlier; however, it would be their last. Their album "Welcome to the Pleasuredome" also reached number 1.

Wham! had their first number 1 single this year after four earlier top 10 hits, the upbeat "Wake Me Up Before You Go-Go". This would soon be followed by their second, "Freedom" later in the year, and their second album Make It Big also reached the top. One of the members of the band, George Michael, also released a solo single this year, the ballad "Careless Whisper" co-written by his bandmate Andrew Ridgeley. It was number 1 for three weeks and sold over a million.

A big-selling singer who would go on to have many hits over the next two decades first appeared this year, American singer Madonna. Her debut hit "Holiday" reached number 6, and "Like a Virgin" charted three places higher at number 3. From the same country came Prince, who had his first two top 10 hits with "When Doves Cry" and "Purple Rain". For both artists, 1985 would bring even more hits as would the rest of the decade.

After eighteen years, Stevie Wonder achieved his first solo number 1 single with "I Just Called to Say I Love You", from the soundtrack of the film The Woman in Red, selling over a million. He had first charted at the age of 15 with "Uptight (Everything's Alright)" in 1966, and had previously had a number 1 in 1982 with a duet with Paul McCartney, "Ebony and Ivory". In 1984 his harmonica playing featured in Chaka Khan's number one hit "I Feel for You" and in 1985 Eurythmics' number 1 hit "There Must Be an Angel (Playing with My Heart)".

The Christmas number one single featured more than 40 artists. "Do They Know It's Christmas?", written by Bob Geldof and Midge Ure, was made in response to ongoing famine in Ethiopia, so the supergroup Band Aid was formed to sing a charity record about it, all proceeds from the song going to the charity to raise money for help. Popular acts of the day such as Wham!, U2, Spandau Ballet, Duran Duran and Boy George sung on the record.

Not only did the song become the Christmas number one, it sold over three million copies and became the biggest selling single of all time, a record that held for the next thirteen years. The song at number 2, Wham!'s Last Christmas, sold over a million and proceeds from that also went to the charity. Further Band Aid singles would be released in 1989 (Band Aid II) and 2004 (Band Aid 20), both also Christmas number one.

The classical year was kicked off by the first complete performances of Oliver Knussen's one act fantasy opera Where the Wild Things Are, based on Maurice Sendak's 1963 children's book of the same title. Knussen composed the music from 1979 to 1983 and an earlier version was first heard in Brussels in 1980. The other major classical music event of the year was the first performances (in the US, then in the UK) of The Mask of Time, the longest and most ambitious of Michael Tippett's late works, written in 1982 by the then 77 year-old composer. Wilfrid Mellers called it "a mind-boggling cosmic history of the universe", while Paul Driver wrote that the Mask revealed "the authentic early Tippett", with a return to the lyricism of The Midsummer Marriage and multiple acknowledgements of his early compositions.
